This IgE ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Guinea pig IgE. This ELISA kit for research use only, not for therapeutic or diagnostic applications!

Preparation and Storage

Store all reagents at 2-8 degree C.

Sample Preparation

We suggest pre-experimenting with neat (undiluted) samples, 1:2 or 1:4 dilutions. Please avoid diluting your samples more than 1:10 as it would exceed the dilution limit set for this kit. If the expected concentration of the target is beyond the detection range of the kit, please contact our technical support team

Product Note

Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved. If the format of this assay is important to you then please request the current manual or contact our technical support team with a presales inquiry before placing an order. We will confirm the current details of the assay. We cannot guarantee the sample manual posted online is the most current manual.

Other Notes

Small volumes of IgE elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS721681 is a ready-to-use microwell, strip plate Competitive ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Immunoglobulin E (IgE) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range of 50-1000ng/mL in biological research samples containing IgE, with an estimated sensitivity of 1.0ng/mL. The ELISA analytical biochemical technique of the MBS721681 kit is based on IgE antibody-IgE antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect IgE antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, IgE. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions such as Serum, plasma, Cell Culture Supernatants, body fluid and tissue homogenate. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Principle of the Assay: IgE ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-IgE antibody and an IgE-HRP conjugate. The assay sample and buffer are incubated together with IgE-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the IgE concentration since IgE from samples and IgE-HRP conjugate compete for the anti-IgE antibody binding site. Since the number of sites is limited, as more sites are occupied by IgE from the sample, fewer sites are left to bind IgE-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The IgE concentration in each sample is interpolated from this standard curve.
